## `[Contest Submission] High-Performance Zcash Co-authorship Network Visualizer in Rust`

Hello Zcash community! 👋

I am excited to share my submission for the **zcash-irondevs** contest. I have built a complete, multi-stage pipeline to extract, deduplicate, and interactively visualize the Zcash ecosystem’s co-authorship network.

Recognizing that parsing decades of Git history across multiple repositories is a heavily I/O and CPU-bound task, I chose **Rust** to ensure maximum speed, memory safety, and reproducibility (achieving a ~100x speedup compared to traditional Python-based approaches).

### Key Features

- **High-Performance Extraction:** Multi-threaded Git history parsing using `git2` and `rayon`, processing thousands of commits per second.
- **Smart Deduplication:** Robust alias resolution that automatically detects email changes in commit messages and resolves complex alias chains (e.g., `A → B → C` correctly resolves all historical commits to the final canonical email `C`).
- **Temporal Graph Aggregation:** Groups commit data by day on the backend, enabling instant, client-side “time-slicing” without overwhelming the browser’s memory.
- **Interactive Web Visualization:** An embedded `axum` web server serves a responsive `Cytoscape.js` bipartite graph. It features:
  - Dynamic date-range filtering with instant recalculation.
  - Keyboard shortcuts (`Ctrl + Arrows`) for quick timeline navigation.
  - A custom logarithmic diagonal layout to prevent node overlap and ensure perfect readability, even with hundreds of contributors.

- **Reproducible:** Fully containerized with Docker for reliable, one-command execution on any environment.

### How to Run

**Option 1: Docker (Recommended)**

```bash
git clone https://github.com/openkoder/zcash-irondevs/
cd zcash-irondevs
docker build -t zcash-network .
# Mount your local data directory (adjust the absolute path as needed)
docker run -it --rm -v /absolute/path/to/zcash-irondevs/data:/data -p 3000:3000 zcash-network

```

**Option 2: Native Rust**

```bash
git clone https://github.com/openkoder/zcash-irondevs/
cd zcash-irondevs/projects/openkoder/zcash_extractor
cargo run --release
cargo run --release -- --serve

```

Then, open your browser and navigate to `http://localhost:3000`.

> _The interactive UI allows seamless filtering of the network by date, instantly updating the layout, metrics, and node sizes._

### Acknowledgments

Thank you to @jenkin and the entire Zcash community for organizing this contest and for the continuous heroic work on the protocol. Exploring the commit history of Zcash and related repositories was a fascinating journey into the engineering foundations of Zcash.

The source code is fully open-source. I welcome any feedback, questions, or code reviews!

#### About the Author & Support

If you find this tool useful, I invite you to support my ongoing work in the Zcash ecosystem. I am currently developing [MonteZecret: A Desktop Wallet for Zcash in Rust](https://forum.zcashcommunity.com/t/montezecret-a-desktop-wallet-for-zcash-in-rust-instead-of-tweets/56164/).

Building secure, native, and high-performance tools for Zcash is my passion. If you would like to fund further open-source development, donations to my Zcash Unified Address are highly appreciated!
